The southern half of Greenland is reacting to what we think is climate warming. The northern half is waiting but I don't think it's going to take long.

These findings call into question predictions of the future of Greenland in a warmer climate from computer models that do not include variations in glacier flow as a component of change. Actual changes will likely be much larger than predicted by these models.

Climate warming can work in different ways, but generally speaking, if you warm up the ice sheet, the glacier will flow faster.

The Greenland ice sheet's contribution to sea level is an issue of considerable societal and scientific importance.

It's likely that Greenland is going to contribute more and faster to rising sea levels than previously estimated.
